SUPPORTING DEVICE FOR RIDGE WITH SLIDE TYPE ELASTIC SUPPORTING DEVICE FOR STRUCTURE AND HORIZONTAL FORCE AND LIFT FORCE ELASTIC RESISTANCE DEVICE, AND INSTALLING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a function separating type supporting device for a bridge of a slide type elastic supporting device for supporting a load of a suitable upper structure for the bridge, etc., for new construction and a horizontal force and lift force elastic resistance device. ;SOLUTION: A lower supporting member 2 and an elastic supporting body 5 compose a slide type elastic supporting device 30 for supporting a load. So, lower and upper steel members 9, 10 of the supporting body 5 are fitted into a shear deformation restraining wall 4 without a horizontal movement. A level of an upper surface of the upper steel member 10 is provided higher than that of the restraining wall 4. An upper structure 22 is slidably supported through a slide-supporting member provided on an upper part of the upper steel member 10. A reaction wall 3 is provided on an upper part of a lower structure 1. One side part of the horizontal force and lift force elastic resistance device 46 having steel longitudinal members 50, 53 at right and left both end parts of an elastic layer 51 is fixed on the reaction wall 3. The other side part of the supporting device 46 is fixed on an upper part of an upper structure 22.;COPYRIGHT: (C)2000,JPO
